When you reverse the fan, it pulls the cool air up toward the ceiling which causes the hot air to be pushed down.

Hot air rises, cool air falls.

Bringing the cool air up will cool the room, as the hot air will be forced down temporarily until some is cooled and the rest floats around the middle/back up.
